摘要
[Objectives] To determine the optimal preparation process of compound Ban Huang oral liquid. [Methods] Orthogonal test and other methods were used to optimize the preparation conditions of compound Ban Huang oral liquid. [Results] The optimal conditions determined were as follows: soaking for 12 h,decocting twice with 2 h per time,concentrating filtrate to 1. 18-1. 25 g/m L at 80 ℃,ethanol precipitating twice with ethanol contents of 600 and 750 ml/L,standing for 24 h. [Conclusions] The optimized preparation process is simple,feasible and stable,and can be used for preparing compound Ban Huang oral liquid.
